CSU DSU | DTE DCE | Data Terminal Equipment | Data Circuit terminating Equipment

In this video we are going to discuss Channel Service Unit (CSU)/Data Service Unit (DSU).
A serial link terminates at CSU/DSU. It is a device providing an interface to connect LAN frame to WAN frame.
WAN uses services from telephone networks, cable networks, satellite system with various different speeds/ clocking
CSU/DSU and router collectively are also known as Client Premises Equipment (CPE).
Data Terminal Equipment (DTE)/Data Circuit-terminating Equipment (DCE)
A device providing clocking information is DCE and a device receiving clocking information is DTE.
Clocking information is required for Synchronization. DTE uses the communication network and DCE facilitate the communications.
Typical example of DCE are CSU/DSU, DSL Modem and Cable Modem and example for DTE are Router and computers
CSU/DSU can be integrated into the router’s serial interface hardware.

teaching with animation is awesome, it helps learning a lot and make sense for any concept understanding.

You are absolutely right, animation helps a lot. Thanks for sharing your views on that.

[@suneeldatta]

It was a nice video..
Can you do some animation describing.. the connectivity between WAN and LAN? What all the different protocols that will be used at WAN level and their frame structures..
What all the different protocols that will be used at LAN level and their frame structure.
How one protocol frame structure on LAN changes other protocol frame structure on WAN..
Better take stream of bits and explain please.
Its really helps.. I am having confusion on this..

Sure, I'll try to cover some general idea in some of my videos in future, meanwhile, I would recommend some related videos, it may help.
